Great Dark Spot
This image of Nar Sulcus in Yalode Crater was obtained by NASA's Dawn spacecraft on May 19, 2018 from an altitude of about 875 miles (1410 kilometers).
Looking back toward the sun brings out the thin haze that hovers 500 kilometers (310 miles) above Saturn's moon Titan. The haze is composed of small particles whose diameter is comparable to the...

The left side of Helena crater on asteroid Vesta has a fresh and distinctive rim. Dark and bright material crops out of this part of the rim and slumps towards the center of the crater in this imag...
Unusual Bipolar Crater
On Tuesday, Sept. 20, 2016, the Cassini spacecraft took its final optical navigation, or OpNav, image of the mission. Throughout its journey Cassini has used its narrow angle camera to capture imag...
Cassini Takes Final OpNav Image
As Cassini sped around Saturn, the spacecraft turned to snap this image of bright spokes giving chase around the B ring. These radial markings are appearing more often as Saturn approaches equinox...

A pair of Saturn's moons appears as if hung below the planet's rings in this Cassini spacecraft view. Enceladus (313 miles, or 504 kilometers across) appears just below the rings here, near the ce...
Shadow-draped Saturn rests on its side as two icy moons glide past. Dione (1,126 kilometers, or 700 miles across) hangs against the planet's bright southern hemisphere. Mimas (397 kilometers, or 2...

Titan's First Close-Up October 26, 2004 This image is one of the closest ever taken of Saturn's hazy moon Titan. It was captured by Cassini's imaging scien...
Titan's First Close-Up
Alternating light and dark bands, extending a great distance across Saturn's D and C rings, are shown here in these Cassini images taken one month before the planet's August 2009 equinox. The C ri...
Extensive Spiral Corrugations
This view highlights tectonic faults and craters on Dione, an icy world that has undoubtedly experienced geologic activity since its formation. To create the enhanced-color view, ultraviolet, gree...

This map of Titan's surface illustrates the regions that will be imaged by the Cassini spacecraft during the spacecraft's second close flyby of Titan on Dec. 13, 2004.
Encountering Titan Again
The Cassini spacecraft casts its gaze across four million kilometers of space for this snapshot of Iapetus, Saturn's most distant major moon. Iapetus -- at 1471 kilometers (914 miles) across -- is...
Taking a Longer View
The sunlight angle in this sharp view of Saturn's second-largest moon, Rhea, highlights the moon's crater-strewn surface. Cassini will fly past Rhea on Nov. 26, 2005, at a distance of only 500 kilo...
Rhea's Ancient Surface
Interesting geological details on Enceladus can be seen in modest-resolution Cassini spacecraft views like this one. At bottom is the wrinkled and generally crater-free terrain near the moon's sout...

Four Ways to See Saturn
Saturn's frigid moon Titan has some characteristics that are oddly similar to Earth, but still slightly alien.
Dunelands of Titan
Lit brilliantly by the sun, the moon Rhea shows off its huge ray crater. The view was obtained at a distance of approximately 812,000 kilometers (505,000 miles) from Rhea and at a Sun-Rhea-spacecr...
With its light and dark surface, Iapetus appears almost like a yin and yang symbol or a comma punctuation mark in this Cassini spacecraft image. See Global View of Iapetus' Dichotomy to learn mor...
